UNITED STATES JAMEs 0. GOULD, F SUMMERVI-LLE,PENNSYLVANIA RA LNUT LOCK A Application filed July 17,'

This invention relates to certain new andv useful improvements in nut locks primarily designed for application upon and for use in ionjunction with rails and fish plates thereor.

An object of the invention' comprehends the provision and arrangement of means whereby the nuts will be lockingly retained. against displacement upon both sides of the Another object of the invention contem- 1 plates the provision of plate members to be carried upon the bolts.

More specifically stated the plate members are provided with nut engaging portions.

With the above and other objects in view, the invention further consists of the following novel features and details of construction to be hereinafter more fully described,

illustrated in the accompanying drawingand pointed out in the appended claims.

In the drawing c Figure 1 is a perspective view of the completed rail joint illustrating the arrangement of a portion of my nut lock. Figure 2 is a view similar to Figure lillus- V trative of the opposed side ofthe rail oint and the complemental locking structure.

Figure 3 is a plan viewof oneof the complemental locking devices'in blank form. I

Referring tothe drawing infdetail wherein like, characters of reference denote c017 responding parts, the reference characters '10 j and 11 indicate the adjacent ends of-=companion rails having fish plates12'arranged thereon across'the joint. Bo1t' members 13 passed through the fish plates and the webs of the rails are also passed through the plate 14 and the eccentrically located openings 14 in the plate. 15 in accordance with the suggested arrangement disclosed in Figures 1 and 2 of the drawing. Two bolts are arranged upon each of the rails but only one bolt passes through the plate 14 as shown in Figure 1.

The ends of the latter mentioned plate are right-angularly bent to provideabutments or nut engaging portions 16. Said plate engages and retains two nuts against displacement. The bolts extending in opposltely d1sposed relation to that of the bolts carrying tightening.

the locked nu'ts are in turn; projected through the openin 14 in the opposed fish plate; as shown inFigure The plate members 15 Y are initiallyaccommodated upon the'project-.

. the ma nner shown leaving finsor projections 18 incident-to the particular formation there- :of. jThese fins or projections" lie flush against the points of intersectionflof the adjacent."

V fish plates between the rail weband'foot en gaging portions. .The arrangement disclosed will look all the nutsupon the bolts em ployed at each rail joint whereby road gangs employed for the sole purpose of tightening joints will be obviated in view of the fact that the initial installation or application is all that is required to establish a-tight joint and does not require periodic inspection and The invention is susceptible of various. changes in its form, proportions and minor details of construction, and the right is here in reserved to make such changes as properly fall within the scope of the appended claims.

. Having thus described the invention, what is claimed is 1." A nut lock comprising an elongated plate'havingian eccentrically located bolt receiving opening, abolt passed through the openingand accommodating a nut, said plate having a slot opening to the opposite end and to one side of the longitudinal center thereof, the wider po tion being reversely bent upon the plate to ispose the extremity thereof in abutting engagement with the immediate portion of the nut, and the narrowerportion beingprojected outwardly in: alignment with the plane of the plate and'in opposed relation to that of the wider portion.

2. In combination a rail'joint including plates connecting the ends of adjacent rail sections, of a plurality of bolts extending through the rail sections and plates, a looking plate bearing against the connecting plate on one side of the joint said locking plate being held in position by one of the sections. of a plurality of bolts extending through the rail sections and plates, a lockin g plate bearlng against the connectin g plate on one side of the joint, said locking plate 7 being held in position by one of the bolts, angular extremities for said locking plate engaging the inner faces of adjacent nuts to hold the bolts therefor against rotation, a final locking plate carried by the mentioned bolt and bearing against the immediate connecting plate upon the opposite side of the joint, the latter mentioned locking plate being split, and a portion of the final locking plate to one side of the split being reversely bent upon the plate to dispose the extremity thereof in abutting engagement With the immediate face of the nut upon the mentioned bolt to hold the latter against rotation.

In testimony whereof I afiix my signature.
